AI Becomes Mainstream in Resume Writing

## The Job Market, Shaken by AI: The Pros and Cons of Soaring 'AI Self-Introductions' An unprecedented wave of change is sweeping through the way job seekers write their self-introductions. Writing self-introductions with the help of artificial intelligence (AI) has now become a mainstream phenomenon, not merely an option. A shocking survey revealing that a staggering 69% of self-introductions submitted in the first quarter of this year were written by AI suggests that the paradigm of the recruitment market has fundamentally shifted. According to Muhayu's 'AI Self-Introduction Trend Report,' compiled through its AI document evaluation service 'Prism,' the proportion of AI-written self-introductions, which was merely 7% in the second half of 2023, surged by more than nine times in just one and a half years, reaching 69% in the first quarter of 2025. Over the entire year of 2024, 48.5% of submitted documents were AI-generated, with a particularly remarkable phenomenon in the second half, where the figure soared to 63%, a 2.7-fold increase compared to the first half (23%). This clearly demonstrates that job seekers actively utilized AI to significantly shorten the time spent on job preparation. However, behind the advantage of efficiency lies a fatal shadow. The average plagiarism rate for AI-written self-introductions was 24.1%, more than double the 9.9% rate for directly written documents. This is a chronic problem that arises when AI learns and recombines similar patterns and phrases, warning that the authenticity and originality of job seekers could be threatened. The utilization of AI for self-introductions is even more pronounced in specific industries, job roles, and types of job seekers. By industry, the financial sector (38.2%) showed the highest utilization rate, followed by private companies (34.6%) and public enterprises (24.8%). By job role, IT/development (27.3%) led the way, followed by research (21.7%) and non-development roles (17.4%). Particularly noteworthy is that the AI utilization rate among new hires and interns (29.7%) was more than 10% higher than that of experienced professionals (18.9%). It is analyzed that those with less job experience more acutely need AI's assistance in information retrieval and content structuring. In response to these rapid changes, the recruitment market is also reacting swiftly. Companies are implementing various efforts, such as introducing systems to detect AI-written documents beforehand and utilizing customized in-depth interview questions to verify the authenticity of self-introduction content and the applicant's actual capabilities. Muhayu's 'Prism' service accurately distinguishes AI-written documents through 'GPT Killer,' Korea's first generative AI detection feature, and checks for plagiarism based on a vast database of 10 billion items, currently being used by approximately 700 companies. Shin Dong-ho, CEO of Muhayu, pointed out, "If companies fail to filter out AI-written self-introductions, it could lead to unnecessary resource waste during the interview stage," and emphasized, "To truly select talent suitable for the job, it is crucial to identify AI authorship beforehand and thoroughly verify the applicant's actual capabilities." AI is now an unavoidable reality, but recognizing its underlying problems and dealing with them wisely has become a task for both job seekers and companies.
